To`lallliurhoai Ltg nary concern:

a eiti'leno the :United tates, and resident of Milwaukee i in thel county of, Milwaukce and State of ljVisconsin, have invented certain new and useful Improvements in Cleaningand `Sterilaing Apparatusg-- and I do hereby declare that the followingis a full,

.ideal-,and 'exact description thereof.

)Myinvention consists in what is herein 'particularly set forth with referencev tothe accompanying drawings and pointed out in claims7 its objectbeing toprovide simple,- economical and eflicient apparatus for thorough cleaning and Vsterilizmg'of milk-cans l,under pressure.' v Y A .Figure 1 ofi-thc drawings represents al front elevation of? apparatus 1u accordance .with Inyinvenlion partlyin section; Fig. 2, ane

.a liorizont-alsection of the same on the'p indicated by line 24-2 in Fig. 1, and Fig. 3,

.a vertical transverse section of a fragment ufsaid, apparatus on' the plane indicated by' ine 31-3 in Fig. 2. 42,5

Referring by numerals to the drawings, 4 indicates the top and 5 the legs ,of a stand.' Surniounting the stand is ajpartly conical er annular '7, and seated in said block, be-

aring flan ange Vand conical portlon of same,

tween the isa packnggasket. The conical portion of-"theblock is annularly'-recessed .for the shank 10.0f' a rose 11 is screw-threaded -in a .vertical center-'bore-,IZ o f the block 6, and intersectingV this bore .ar'e' converging ports 13 and 14 with which the' `lowerportion 'of f said-block is provided. VThese ports and the v hore;.co1nnion to both constitutewjinlets to which reference is had in `the claims.r `P a'allel-to' thebore12 is anothcrborc lintersecting a drain-port 16y in lthe lower portion offthe .aforesaid block and' therewith consti'- 'tuting an 4outlet to-which reference is had in the' claims. A cock-controlled water-.induction pipe 17 eonnectswith'the port 13, a

cock-controlled steun-induction-plpe 18 connects with the,inlets-port.4 14, and a cock-controlled' wastepip'e .19 4conneetswith the outlA .t -port 16,-th1sppe bein'g'provided ivith'a vided, the clampedgcan has water and steamfn 100.

CLEANING AND STERILIZING AP'PARATUS.

The tubular V branch 20 in connection with a port 21 in -,Be it known-'that'L JARED J. IIaATuco'rE,'

the block-flange 7. 4 l

.He-ld in vertical apertures of the top 4 .of the stand, byuppcr und lower nuts 22, 23 are tubes 24, and nuts are run in the upper ends ofthe tubes. The nuls 23 and 25 are fashioned to constitute lguide-sleeves for a pair of rods 26 that are rigidly secured at their low'er ends lo a yoke 2i' below the top of the aforesaid stand. A counter-weighted ireadlc-l'cvcr 2S is pivotally connected to a pair of salue, and fulcrulned in ay forked bracket 3() depending from the top of the stand above specified. Depending from the top of the stand'is a rackbar Blwth which to engage the lever and thereb7 lock the same out of -.normal position.

Supported upon the-sleeve-'nuts 25, under lcusiolrnnts 32,011 the rods 2G, are spiralsprings, 33, and at rest on saidrtcnsion-nuts isa yoke 34 engaged by said rods. Opposing the lyoke 34, above the same, are spiralsprings 35 on the rods 2G under tension-nuts 3G that are run on the upper ends of said' rods. The rods and yokes aforesaid constitute a frame, and the yoke 34 is provided with a center bearing for a screw-threaded stein 37 fast at its upper end in a. hand-wheel 38,-the lower end of the stem being loose in e. central socket of a spider 391 -A screw 40 carried by the spider entends into an annu lar groove of the stem and thus said spider is held in detachable connection with said stem.

As herein shown itis preferable to tit a reduction-valve 41 andapressure-gage 112 in connection. with. the steamiruluction pipe above specified.

In practice, a 1nillr-ca11 is inverted on the block as shown byl dotted lines in Fig. 1, and the, lever 2S depressed and engaged 4with the 'raclobar 31 to clamp said can in place, by means of the spider 39 that is independently ad'usta-ble to compensate for cans of varying cngth, the internal pressure upon the can being variable in proportion to the depression of the lever. Because of the packing with which the block 6 is pro` Specicatlan of Letters Patent; Pieni-,ed Mar, 7 v1,911, 1 application mea Novemer 22, 190s. serial No. 529,245.

depending yoke-cars -Sl, between the cans by 'steam under pressure within the and a steam passage, 'tical rods andguides lever-controlled yoke i wash and rinse the can, positione as afore said, water under pressure is let on from the pipe 17 to flow in jets from the rose 11, the

pipe 19 being opened to p ermit` escape of the waste water. The washing and rinsing havingbeen accomplished, the water is eutof, the Waste-pipe closed andstcam from 'the pi e 18 admitted to the canin jets tliroug the rose 11 to sterilize said can, after which the steam is cut-off and said waste-pipe opened to permitthc escape of water of condensation. On removal of the can any drippings therefrom within the contines of t-he block-fian e 7 will find their way to the drain-pipe tirougli the branch 2O of saine. Should the pressure in the can 'at ang7 time exceed the tension of the springs 35, said can will lift from its clamped position to relieve said pressure, acting to return said can to said ositon, and when the. lever 28 is released rom the rack-bar 31,' the.. previously contracted springs 33 expand to return the movable parts of theapparatus to normal position.

B'y means of the apparatus above specified the washing and rinsing of milk cans can be rapidly and thoroughly accomplished and perfect sterilization of said cans effected in an economical Way, susceptible of variation in matters of detail withoutdeparture from the scope. of my in`A vention as herein claimed, especial attention being called to the sterilization of the saine, whereby said Vcans are subjected to a much higher temperature than can be otherwise attained, provision beingliad for varying the external pressure upon the canat the will of the operator in proportion to the steain-pressure desired to be maintained within said can for an indefiniteperiod to .effect a thorough-sterilization ofthe saine.v
